The Application of Digital Techniques to the Measurement of Loudspeakers

A new approach to the problem of the measurement of loudspeaker characteristics is presented. A digital processor is used to obtain the loudspeaker's transfer function from a direct measurement of the impulse response. The measuring method is discussed in detail along with the forms of display which have so far been used. Some applications are discussed briefly. Finally, the method is shown to be suited to a system approach to the study and development of loudspeakers.
